* This is a main class to run the UPA Value Add Provider application. *

*

Summary

*

* The purpose of this application is to demonstrate interactively providing * data to OMM Consumer applications using ValueAdd components. It is a * single-threaded server application. *

*

* The provider application implements callbacks that process requests * received by the consumer. It creates a Server and a Reactor and * waits for connections. It accepts these connections into the Reactor * and responds to messages through its Login, Directory, Dictionary, and * default message callbacks. *

*

* This provider supports providing Level I Market Price, Level II Market By * Order, Level II Market By Price, and Symbol List data. Level II Market By * Price refresh messages are sent as multi-part messages. An update * message is sent between each part of the multi-part refresh message. *

*

* Batch requests are supported by this application. The login response message indicates * that batch support is present. Batch requests are accepted and a stream is opened * for each item in the batch request. *

*

* Posting requests are supported by this application for items that have already been * opened by a consumer. On-stream and off-stream posts are accepted and sent out to any * consumer that has the item open. Off-stream posts for items that have not already * been opened by a consumer are rejected (in this example). *

*

* Symbol List requests are expected to use a symbol list name of "_UPA_ITEM_LIST". The * symbol list name is provided in the source directory response for the consumer to use. *

*

* This application is intended as a basic usage example. Some of the design choices * were made to favor simplicity and readability over performance. This application * is not intended to be used for measuring performance. This application uses * Value Add and shows how using Value Add simplifies the writing of UPA * applications. Because Value Add is a layer on top of UPA, you may see a * slight decrease in performance compared to writing applications directly to * the UPA interfaces. *

*

Setup Environment

*

* The RDMFieldDictionary and enumtype.def files must be located in the * directory of execution. *

*

Running the application:

*

* Change directory to the Java directory and issue the following Gradle command. *

* Linux: ./gradlew runVAProvider -PcommandLineArgs="arguments"
* Windows: gradlew.bat runVAProvider -PcommandLineArgs="arguments"
*
* Arguments are listed below. *
